#1431: edmunds_karp_max_flow fails to compile with bundled residual capacity
---------------------------------+------------------------------------------
 Reporter:  kukkerman_at_[hidden]  |        Type:  Bugs            
   Status:  new                  |   Milestone:  To Be Determined
Component:  None                 |     Version:  Boost 1.34.1    
 Severity:  Problem              |    Keywords:                  
---------------------------------+------------------------------------------
 If edmunds_karp_max_flow is called with a map created with
 {{{get(&edge_bundle::residual_capacity, graph)}}} from the bundled
 residual capacity property then the source fails to compile.

 The problem is as follows:[[BR]]
 In filtered_graph.hpp the {{{is_residual_edge}}} predicate has a default
 constructor:[[BR]]
 {{{is_residual_edge() { }}}}[[BR]]
 [[BR]]
 But it also has a member:[[BR]]
 {{{ResidualCapacityEdgeMap m_rcap;}}}[[BR]]
 [[BR]]
 Bundle property maps have the following constructor only:[[BR]]
 {{{bundle_property_map(Graph* g_, T Bundle::* pm_)}}}[[BR]]
 [[BR]]
 So in the case of a {{{bundle_property_map}}} the {{{is_residual_edge}}}
 predicate declaration is invalid because it's default constructor
 implicitly calls the default constructor of {{{m_rcap}}} which doesn't
 exist.
